Which theory suggests that belief in the ability to succeed leads to healthier behavior?

Self-Efficacy Theory is a psychological concept introduced by Albert Bandura, which centers around the belief in one’s own capabilities to successfully perform tasks and achieve goals. This theory posits that when individuals have confidence in their ability to effect change and succeed in specific situations, they are more likely to engage in healthier behaviors.

For instance, a person who believes they can successfully adhere to a diet or exercise routine is more likely to implement those healthy choices consistently. This self-belief fosters motivation and resilience in the face of challenges, enabling individuals to seek out resources, overcome obstacles, and remain committed to their health goals.

In contrast, the other theories listed do not focus primarily on the individual’s belief in their abilities as a critical driver for health behavior. Family Systems Theory looks at how family dynamics and relationships affect behavior rather than individual self-belief. Systems Theory is broader, focusing on interrelated parts within a complex system. Health Belief Theory emphasizes perceptions about health risks and benefits but does not specifically address self-efficacy as a key component in driving healthy behaviors. Thus, Self-Efficacy Theory distinctly highlights how the confidence in one's abilities influences health-related actions.
